Lipid metabolism - 24.3 Lipid Metabolism

In fat metabolism the liver cells break down fats and produce energy.

Overview of Lipid Metabolism

For example, very-low-density lipoproteins carry the synthesized triglycerides by our body and LDL transport cholesterol to our peripheral tissues.

Bile is produced by your liver, stored and released in your gall bladder and emulsifies fat globules into smaller droplets.

The newly formed acetyl CoA enters the Krebs cycle and is used to produce ATP in the same way as acetyl CoA derived from pyruvate.

Lipid metabolism

Although there are several metabolic sources of acetyl CoA, it is most commonly derived from glycolysis.

The legacy of this great resource continues as the MSD Manual outside of North America.

Ketones serve as fuel in times of prolonged starvation or when patients suffer from uncontrolled diabetes and cannot utilize most of the circulating glucose.

Lipid metabolism

Lipoproteins synthesized by the liver transport endogenous triglycerides and cholesterol.

Description: This process, called lipolysis, takes place in the cytoplasm.

The long-chain acyl-CoA enters the fatty acid β-oxidation pathway, which results in the production of one acetyl-CoA from each cycle of fatty acid β- oxidation.
The chylomicrons enable fats and cholesterol to move within the aqueous environment of your lymphatic and circulatory systems.

    Lipid metabolism entails the oxidation of fatty acids to either generate energy or synthesize new lipids from smaller constituent molecules. Lipid metabolism is associated with carbohydrate metabolism, as products of glucose (such as acetyl CoA) can be converted into lipids. Triglyceride Broken Down into a Monoglyceride

    Major Apoproteins and Enzymes Important to Lipid Metabolism Lipids are fats that are either absorbed from food or synthesized by the liver. Triglycerides (TGs) and cholesterol contribute most to disease, although all lipids are physiologically important.

    The body draws energy from lipid metabolism during exercise. Lipid metabolism is the process by which fatty acids are digested, broken down for energy, or stored in the human body for later energy use. These fatty acids are a component of triglycerides, which make up the bulk of the fat humans eat in foods like vegetable oils and animal products.

    The major aspects of lipid metabolism are involved with Fatty Acid Oxidation to produce energy or the synthesis of lipids which is called Lipogenesis . Lipid metabolism is closely connected to the metabolism of carbohydrates which may be converted to fats. This can be seen in the diagram on the left.

    Lipid metabolism is altered in cancer—tumor cells reactivate de novo lipid synthesis, ATP-citrate lyase is required for transformation in vitro, cholesterol synthesis in prostate cancer is increased, and fatty acid oxidation is an important source of energy for prostate cancer cells (Santos & Schulze, 2012).
